Hereinafter, the description will be made with reference to FIGS. 6 and 7. A lever 2 is rotatably attached to the connector housing 1, and a pair of arms 3, 3 of the lever 2 come into contact with the projection 8 of the connector housing 1 when the lever 2 is rotated. A flexible piece 4 to be bent is provided.

る。To fit the connector housing 1 and the mating connector housing 6, the lever 2 is turned,
The protrusion 7 of the mating connector housing 6 is guided by the cam groove 3A of the arm 3. When the connector housings 1 and 6 are completely fitted, the lock 5 of the lever 3 is engaged with the receiving portion 1A of the connector housing 1. When the lever 2 rotates, the flexible piece 4 abuts on the protrusion 8 and is bent, and a force is stored that pushes the lever 2 back in the opposite direction (the direction in which both connector housings are separated) (see FIG. 7). ). If the rotation operation of the lever 2 is stopped irrespective of the two connector housings 1 and 6 being in the half-fitted state, the lever 2 is pushed back by the stored force, and it can be detected that the lever 2 is half-fitted. It has become.

いう問題があった。However, in the above-described lever-type connector, the flexible piece 4 is provided at a position offset from the rotation axis of the lever 2 (reference numeral F in FIG. 7). The direction of the reaction from the protruding portion 8 to the flexible piece 4 (in the direction of arrow A in FIG. 7) does not match the direction of the couple of the moment in the lever 2 (in the direction of arrow B in FIG. 7), and the force transmission efficiency Gets worse. As a result, there is a problem that the push-back force of the mating connector housing cannot be effectively obtained.

According to the invention, a lever including a pair of arm portions and a rotation operation portion for connecting the arm portions is rotatably mounted so as to straddle the connector housing. In the lever-type connector for bringing both connector housings into the fitted state, the arm portion is formed with a cantilevered flexible piece that can be bent and deformed, and when the lever is rotated in the direction in which the two connector housings are fitted together. The cantilevered flexible piece can be urged in a direction to separate both connector housings by contacting a protrusion disposed on an opposite portion of the connector housing on which the lever is not provided. The contact portion of the cantilevered flexible piece with the protrusion is formed so as to extend substantially in the radial direction of a circle centered on the rotation center of the lever. It is a lever-type connector to the butterflies.

During this time, the cantilevered flexible piece gradually stores the force for pushing back the lever, but according to the invention of claim 1,
The portion where the cantilevered flexible piece abuts on the protrusion extends almost radially with respect to the center of rotation of the lever. It almost matches the direction of the force used to force it. Therefore, the force stored in the cantilevered flexible piece can be efficiently used as the force for pushing back the lever for half-fit detection.

The base portion extends from the arm portion so as to cross the radial direction from the vicinity of the center of rotation of the lever, and only the contact portion with the protrusion is bent, so that the length of the cantilevered flexible piece can be easily set to be long. Accordingly, an excessive force acting on the cantilevered flexible piece can be avoided.

6 are formed. The space 36 extends from the vicinity of the bearing hole 33 so as to be substantially parallel to the cam groove 35, and includes a cantilevered push-back piece 40 (in the present invention) along the inner peripheral surface 36 </ b> A. (Corresponding to the "cantilevered flexible piece"). The push-back piece 40 has a fixed end near the center of rotation of the lever 30 on the inner peripheral surface 36A, and a radial direction of a circle centered on the center of rotation (for example, the direction of a symbol L shown in FIG. 2). And only its tip 41 is bent outwardly along the radial direction described above.

ネクタ全体を小型に製作できるという効果を奏する。When the lever 30 is rotated in a direction in which the connector housings 20 and 11 are fitted, the distal end portion 41 has a protrusion 25 before the flexible lock 34 engages with the engagement portion 22. Abut. When the lever 30 is further rotated from there, the push-back piece 40 is pressed by the protrusion 25 and bent while the flexible lock piece 34 and the engagement portion 22 are locked, and the lever 30 is moved. The force to push back in the opposite direction is stored. As described above, since the push-back piece 40 has only the tip 41 required for contact in the radial direction of the circle centered on the center of rotation, and the entire other extending in the direction crossing the radial direction, There is no need to greatly extend the interference area when the 30 is rotated from the interference area of the arm 31. Therefore, there is an effect that the entire lever-type connector can be manufactured in a small size while having a relatively large push-back piece.

的に回動させて表してある。Further, since the distal end portion 41 extends in the radial direction of a circle centered on the center of rotation, the direction of the force received from the projection 25 coincides with the direction of the force for rotating the lever 30, and the pushback piece is pushed. There is an effect that the force stored in the lever 30 is efficiently used as a force for pushing back the lever 30. In addition, there is the following effect. The effect is shown in FIG.
In comparison with the case where 1 is not extended in the radial direction, the description is as follows. In FIG. 4, only the surface of the push-back piece 40 on the side facing the protrusion 25 is extracted and drawn. Further, the state in which the lever 30 is rotated and the push-back piece 40 is bent is shown by rotating the protrusion 25 relatively to the lever 30.

Is bent at substantially the same angle (D2 in the figure) as the rotation angle of the lever 30 (D1 in the figure). On the other hand, when the tip of the push-back piece is not bent, as shown by reference numeral Y2 in the figure, the protrusion 25 moves along the push-back piece and the amount of pushing in the direction of bending is small. As shown by reference numeral D3, only an angle smaller than the rotation angle D2 of the lever 30 (reference numeral D3 in the figure) can be bent.

The first cam receiving projection 14 is introduced to rotate the lever 30. Then, during the rotation, the tip 4 of the push-back piece 40
1 comes into contact with the projection 25 (see FIG. 2). When the lever 30 is further rotated from this state, the push-back piece 40 is bent at its free end by being pushed straight by the protruding portion 25, and
When the connector housing 11 and the connector housing 20 are completely fitted with each other, a force for rotating the housing 0 in the opposite direction is stored.
The flexible lock 34 and the engaging portion 22 are engaged, and the lever 30
Will not return in the opposite direction.

Is in the middle of rotation. Here, the problem is that, just before the flexible lock 34 engages with the engagement portion 22, the posture remains in a state where it is difficult to detect that the flexible lock 34 is in the half-fitted state. However, in the present embodiment, in the process of rotating the lever 30 and fitting the two connector housings 11 and 20 together,
The push-back piece 40 is pushed straight by the protruding portion 25 at the distal end portion 41, is sufficiently bent, and can accumulate a large reaction force. Further, the reaction force can be efficiently converted into a force for pushing back the lever 30. Thus, even if the operator stops the rotation operation in a state where the flexible lock 34 is not locked to the engagement portion 22, the lever 30 is moved by the reaction force of the push-back piece 40.
It is pushed back to the state shown in FIG. 2, and the operator can detect that it is half-fitted.
